No!
This won't do! After incinerating the last white mouse corpse, Chiba frowned tightly, his face filled with gravity.
It was noon on the day after he had gone out to eat with Yukina. It was almost time for lunch, and he had spent the entire morning trying to improve Higan again.
But it was still failure after failure after failure! Just like yesterday, he remained completely at a loss, without the slightest progress. This was not something that could be accomplished in a day or two. Even Tsunade measured such work in months and years. No matter how capable he was, he could not escape that timeframe.

And right now, time was still quite tight. He could not afford to spend it like this.
At this point, he truly needed to seek out Yuriko instead of continuing with these slim hopes of improvement.
